4.4 Drawbar hitches
4.4.1
General information
Drawbar hitches of “BELARUS-952.5” with hydraulic lift can be packaged with
drawbar hitches DH-2V (short towing yoke), DH – З V (long towing yoke), DH -2R (py-
thon), DH -1 (crossbar), DH-1ZH-01 (twin crossbar), and DH -1 М -01(draw bar), ensur-
ing coupling and transporting of trailed and semi-trailed implements coupling devices of
which correspond to the following requirements:
- compatibility according to the coupling dimensions;
- implements are equipped with rigid drawbar hitch;
- draft poles are equipped with a device making the procedure of cou-
pling/uncoupling with drawbar hitch of a tractor easier;
- drawbar hitches of semitrailers have an adjustable support.
Tractor “BELARUS - 952.5” with hydraulic lift has special-purpose rear mounting
device of lift type in the form of guide plates with several borings fixed to the rear joint face
of a rear axis body. The device is meant for mounting of drawbar hitches and allows height
adjustment of DH-2V (short towing yoke), DH-2R (python) and DH-3V (long towing yoke).
Installation variants scheme of DH-2V (short towing yoke) is shown in Figure 4.4.1.
Installation variants scheme of DH-
З V (long towing yoke) is shown in Figure 4.4.2.
Installation variants scheme of DH-2R (python) is shown in Figure 4.4.3.
Installation variants scheme of DH-1
М -01(draw bar) is shown in Figure 4.4.4.
Installation scheme of DH -1 (crossbar) is shown in Figure 4.4.5.
Installation variants scheme of DH -1 (twin crossbar) is shown in Figure 4.4.11.
Drawbar hitches of BELARUS-952.5 with draft control unit can be packed with coupling
elements DH-2 (hydraulic hook), DH-1M (floating drawbar), DH-1M-02 (combined drawbar hydrau-
lic hook+ floating drawbar), lowering link, DH-1ZH (crossbar) and DH-1ZH-01 (twin crossbar) en-
suring coupling and transporting of trailed and semi-trailed machines (if DH-2 – semitrailes
is installed) coupling devices of which correspond to the following requirements:
- compatibility according to the coupling dimensions;
- implements are equipped with rigid drawbar hitch;
- draft poles are equipped with a device making the procedure of cou-
pling/uncoupling with drawbar hitch of a tractor easier;
- drawbar hitches of semitrailers have an adjustable support.
Installation variants scheme of DH-2 (hydraulic hook) and DH-1M-02 with hydraulic
hook in operation position is shown in Figure 4.4.6.
Installation variants scheme of DH-1M-02 with floating drawbar (DH-1M) in opera-
tion position is shown in Figure 4.4.7.
Installation variants scheme of DH-1M (floating drawbar) is shown in Figure 4.4.8.
Installation variants scheme of lowering link is shown in Figure 4.4.9.
Installation scheme of DH -1ZH (crossbar) is shown in Figure 4.4.10.
Installation variants scheme of DH -1ZH-01 (twin crossbar) is shown in Figure
4.4.11.
The rules of hydraulic hook DH-2 and floating device DH-1M repositioning in combined
drawbar DH-1M-02 from additional position into operation position and from operation position
in additional position are given in subsection 4.4.14 „Repositioning of coupling elements in
combined drawbar DH-1M-02“.
Basic parameters of drawbar hitches shown in Tables and in Figures of subsection 4.4
„Drawbar hitches“ are given with standard rear tires (18.4R34 – both single and dual
mounted to the tractor with FDA 822-2300020-02/04; 16.9R38 – both single and dual mounted
to the tractor with FDA 72-2300020-
А -04)
and with standard static radius, specified by the
manufacturer.
